hello guys, sorry for my english (no mother language)
I have a huawei p9 lite unbranded vns-l31 c432.
turned off the device for the night and suddenly the nex morning turned on......and from that time it can''t connect to the mobile operator anymore.
I have tried various step, to understand if the problem is on the operator or on my device.
Tryed the scanning of the net manually, It can see all network around, meaning the radio function is working. But I can connect to the radio of my operator (and obviously of other carriers)
- tried the sim card on other phones and it is fully working
- tried another sim card of the same operator and it doesn't work on my phone
- tried other sim cards of others operators and they magically work
so I really don't understand this. The operator obviously tells me that if the sim card is working on other phones this means that it is fully working.
If other sim cards don't work on my phone maybe it could be the phone. but the phone is fully working with any sim card from others mobile operators.
my phone is unbranded and fully worked with any operators in these 2 years I have been owning it.
the operator tells me that they can block IMEI number for security reasons in very limited cases, but this is not my situations, since the phone wouldn't work with any operator.
I have tryed to roll back from android 7 to android 6 b161 release. and from b161 to the latest one, android 7. every step I have checked baseband version, wich is always changed. but in none of the firmware version the phone worked.
any idea?
thanks a lot

Okey so ive had my diamond for 3 weeks and have had this issue. The device worked fine for 2 weeks except for this problem that it keeps dropping the connection and just says "no service" but when i disable and re-enable the phone radio i get full signal. However one time the device froze and i had to soft reset. After which it said the "sim card is missing, you can make emergency calls if your service provider supports it" when the sim card was in the phone. I tried resets and cleaning the sim all to no avail. So after not being able to find anyone else with this problem i figured it must be my old 2g sim that had been causing the problems so i went and purchased a new 3g sim from my service provider (mobilezone [switzerland]) and inserted it into the device. Everything starts working again and i figure the problem is fixed. However the phone continues to drop the signal again and again over the next few days and finally kills the sim card again, and displays the same "sim missing..." error. So i have now taken it back to the retailer and they say there seems to be no issue with the device as the technichen inserts a new sim and everything works fine. The thing is that the sim cards are completely broken. They no longer work in any device!!! But it took 2 weeks the first time and 3 days the second, so the technicians agreed to test the device for a couple days, im just sure its gna work fine for that amount of time but screw up again after when i use it again. Can anyone provide any insight into this? I speculate that its perhaps an issue with my service provider since they do not have their own network but use orange (switzerland) with their custom network settings, and when configuring the device the WM6 connection wizard only has 3 options and my provider is not listed, so i use the orange config settings, which i thought may be slightly different and cause problems. Ideas?!?!?
Thanks in advance.

If it helps, I had to have a new sim to use it in my new phone (not the diamond, a nokia) because it didn't work properly, as it was a relatively old sim.
Hi did you ever get your sim problem sorted, have been experiencing same,
except my sim still work on other phones?
Hello friends, how are you?
My name is Renato and I'm from Brazil. Some weeks ago I bought a Galaxy Note N7000 unlocked by TIM operator. It comes with
android 4.0.3 and I never updated the android or did any hacks.
Well, until yesterday, everything was fine. But yesterday, when the phone starts, it find the operator's signal but after some seconds it enter on the
emergency calls only status. Also, even it's blocked for emergency calls only, I can use the internet 3g without a problem! Very very strange...
I already checked my sim card and It works on my older nokia without a problem. Also, I put another sim from another operator (Oi operator) and it works without a problem too. Also I check my sim status at my operator and it´s unblocked too. I did a factory reset too and nothing changes...
Looks like my galaxy note cannot work with TIM sims anymore?
Please if somebody have an idea about this error, please let me know.
Hey guys,
I am in Spain. I asked Sprint to SIM unlock my phone before I left and they said it worked but it did not. I bought a movistar SIM and all I get is 'no service.' Under Cellular+SIM options, it is in CDMA only mode and the option to change it is greyed out. I was in 8.1 so I flashed to 8.0.10328.78 and called Sprint. They want me to update my network profile to send the command to unlock it but it isn't working over WiFi.
The phone knows that the SIM is there, I can access the SIM applications, read the SIM ID and when I turn on the phone with it inserted it says 'switched to CDMA only.' So I think it is still SIM locked. Is there a way I can unlock it? I've never had to deal with this before.
No ideas? I need to know whether I should give up and try to return the plan I bought.

Can Sprint version Ativ S neo unlock ?
Agreed
Just adding to the overall knowledge base here.
I am experiencing the exact same problem.
1. I purchased my phone unlocked (though it was previously on Sprint). I have previously been able to use foreign SIM cards (in France), without issue.
2. At some point, I installed the Developer's Preview of WP8.1 and lost the ability to roam domestically or internationally.
3. I am now in Israel, and tried an Israeli SIM card, but it was on a GSM network. It connected to the network, but showed up as international roaming. Ooops, guess I need to fix that little WP8.1 Beta issue...
4. I decided to flash my phone back to WP8 GDR3, which seems to have un-unlocked my phone. Now when I plug my Israeli SIM card in, my phone automatically switches to CDMA mode.
5. However, if I pop a Sprint SIM card in, I have the ability to switch to Global Mode again.
I have the MSL, but I cannot figure out where I would enter it to get this to stop happening.
FYI.
I had a problem , I live in Ukraine , my phone was unlocked , but when I installed 8.0 my phone worked only in CDMA mode with a Sim card from my service , I updated to 8.1 again using the preview for developers and settings again appeared global regime.
Hi,
I got the update to android 10 yesterday and installed it. My provider is Vodafone DE.
After update, I'm not able to make any calls (or receive ones) anymore.
I already figured out, that this problems does not exists when I'm disable 4G and switch to 3G only.
I also tried out another carrier (Telekom DE), there the problem does not exists (VOLTE is activated).
I cleaned the cache of phone app and google play services. I also already resettet the network several times.
Any more suggestions what could be problem / how to make phone calls working with 4G enabled?
Hi,
I have exactly the same problem, after update to ANdroid 10 no phone calls with 2G or 4G via vodafone in Germany, SMS and (apparently most of the time?) mobile data works in all 2G/3G/4G; another SIM card from the german provider Telefonica/O2 (under the lable BLAU) works fine; the Vodafone SIM also works in my old mobile.
I noticed something else: in the SIM-card settings (where e.g. the color can be chosen for SIM 1 or 2), while under "Mobilfunkanbieter" for the BLAU-SIM card, there appears O2 -.de, vor the vodafone card, it sais "unbekannt"
Did you already find a solution?
I ordered a new Vodafone SIM, same problem; even resetting the whole device to factory mode didn´t help.
Probalb you are aware of a similar (yet apparently sifferent) problem with Nokia 8.1 in automn (I´m not supposed to post URLs here, you may prbably find it yourself in the vodafone forum, the thread there is in German)?
Hi Everyone
I purchased a second hand s20 6 months ago and i am no longer getting any network carrier coverage.
I took my phone to local mobile repair shop and they identified that my base software was South Korean for some reason so they factory reinstalled Android 12 with UK Software. (This still does not work and they are stuck trying to solve the problem)
I'm fairly certain that this issue started when i upgraded from Android 11 to 12.
Please can anyone suggest a possible solution for my phone problem?
Things i have done so far:
1.) Factory reset phone several times including separate network resets.
2.) Tested my new replacement Virgin sim card in 2 other phones (This works)
3.) Tried several working sim cards in my s20 phone (None worked)
4.) Confirmed my phone is not barred or locked.
5.) Checked that i can see other Mobile network operators (Does not connect when i select my provider)
6.) Tested in other cities to confirm it's not a signal coverage issue.
7.) And finally, my phone has the latest Android 12 updates inc local app updates
Thank you
Just to add a further update, i have managed to get my phone working intermittently through WIFI but i still have an issue when outside my home.

Your phone can be in the blacklist as some unpaid fees in the contract of origin provider you purchased this phone. I had exactly same problems and after pay all over due bills phone went into normal.
My S20 Ultra LTE keeps detecting a ghost SIM in the second SIM slot and is making my phone lost signal. Is there a way I can convert it from dual SIM to single SIM?
